Application filed May 25,1911. Serial No. 629,299.

To all whom it may concern:

Be it known that lf, ROY T. AXE, of Syra cuse, in the county of Onondaga and State of New York, have invented a certain new and useful Spring-Roller, of which the following is a specification.

My invention has for its object the production of a spring rollerfor raising windows, curtains, etc., which is particularly simple in construction, economical in manufacture, and highly efficient and durable in use; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters `designate corresponding parts in all the views.

Figure 1 is a longitudinal sectional view, partly broken away, of a roller embodying my invention. Fig. 2 is a cross sectional view on line iA-A Fig. 1. Fig. 3 isan end view of one of the axles of the roller.

1 is the body of the roller, the same being a metallic cylindrical shell formed of a strip of sheet metal rolled into cylindrical form, and having the edges thereof interlocked as shownat 2, Fig. 2.

3 is a head at one end of the cylindrical shell 1 for supporting one of the axles of the roller, and 4 and 5 are heads in the other end portion 0f the shell 1 for supporting the other axle. The'head 3 is composed of sheet metal and comprises a discoidal body having an annular or cylindrical marginal fiange 6 extending within the shell 1 and fitting the inner face thereof, and also having an -axial opening, the margin 7 ofthe wall around the axial opening being turned inwardly forming a hub or bearing for the axle to be described. rlhe free edge of the annular flange 6 abuts against an internal shoulder 8 consisting of a circumferential corrugation in the shell 1, and said head is held in position by turning .the margin at one end of the shell 1 inwardly on the out-er face of thev head 3 as indicated at 9. The flange 6 is formed with openings 10 which are alined with openings 11 formed in the contiguous end of the shell 1 and spaced around the same.

The head 4 is located near the extreme end of the shell 1 opposite to that provided withthe head 3, and the head 5 is located some distance within the shell 1 and is spaced apart from the head 4. Each of the heads 4, 5' consists of a sheet metal disk fitted to the shell 1 and having an axial offset portion 12 or 13 formed with openings fory receiving the axle 14. The head 5 abuts against an internal annular shoulder 15 formed in the same manner as the shoulder 8, and the head 4 is held in position by the inturned margin 16 of the end of the shell 1, and such heads 4, 5 are spaced apart by the interposed portion of the axle 14 which is provided with integral shoulders 17 pressed therefrom and engaging the opposing faces 0f the disks 4, 5 or the offset `parts 12, 13 thereof for holding the heads 4, 5 against the inturned margin 16 and the shoulder 15. The axle 14 is rof 1912, upon an application divisional hereof. v

19, 2O are the members constituting the anchor for the spring of the roller, each of said members preferably having a discoidal head and an annular cylindrical flange, the heads being spaced apart and constituting the end heads of the anchor, the flanges projecting from the margins of the opposing side faces of the heads, and the flange of one member fitting the inner face of the shell -1 and the flange of the other member' telescoping within the flange fitting the shell 1. The members 19, 2O are also formed with a bearing for the axle to be described. In the illustrated embodiment of my invention, the member 19 is formed with an annular cylindrical fiange 21 fitting the shell 1 and projecting laterally from one side face of the main part of the member 19, and with an axial inset boss 22 proje'cting from said side face and the member 2O is formed with a flange 23 tting within the flange 21 and abutting at its free edge vagainst the head of the member 19, and

the member 20 is also formed with an axial opening 24. The members 19 and 2O are secured to the shell 1 by sui-table fastening means 25 extending transversely through the shell 1 and theV flanges 21 and 23.

26 and 27 are elements of the axle, which is fixed from rotationvwith the shell 1 in the normal operation of the roller, the section 26 being journaled in the bearing 7 of the head 3 and having at its outer end a trunnion 28 projecting beyond the outer face of the disk 3, and the section 27 comprising a sleevereceiving a portion of the section 26 arranged on the inner side of the bearing 7, the section 27 extending through and being journaled in, the opening 24 of the anchor disk v20, the inset boss 22 of the member 1.9 of they anchor extending into the axial passage of said section 27 and the end edgeof the section or tube 27 surrounding such axial passagev being seated against the opposing surface of the anchor member 19 and around the boss 22.

y29 is a torsion spring coiled about the axle. section 27 and having a portion 30 at one end extending through openings 31 and 32 in the heads of the anchor members 19 and 20 in order to secure the spring to such anchor, the opposite end of the spring being extended through the section 27 and into the section 26 as indicated at 33.

34 is a discoidal head formed of sheet metal and mounted on the axle section 26 l and rotatable therewith, said head 34 havf be brought into alinement with the openings 10 and 11 of the flange 6 and the shell 1 respectively. The head 34 is secured to the section 26 and is provided with lugs 37 projecting into its axial opening, each lug 37 fitting lengthwise peripheral grooves 38 formed in the section 26.

After the parts of the roller have been assembled, the spring is tensioned by turning the axle section26 by a suitable tool engaged With the trunnion 28. and the spring is held under tension until the roller has been mounted in position and the Window or curtain connected thereto. rlhe spring is heldunder tension by means of a suitable locking lmember inserted through the aliiied openings 11, 10 and 36. Wwhen the roller has .been placed in position and the Window or otherparts attached thereto, such locking member is removed permitting the spring to exert its tension on the part connected to the shell Thisvspring roller is economical of manufacture in that the cylindrical shell, the heads, anchor and other parts thereof y*are formed of sheet metal.
